METAL WHEEL-HUB.

SPECIFICATION forming part of Letters Patent No. 719,281, dated January27, 1903.

Application filed May 21,1902.

To all whont it 7714.47 concern:

Be it known that I, EDWARD R. WAGNER, a citizen of the United States,residing at Milwaukee, in the county of Milwaukee and State of'Wisconsin, have invented certain new and useful Improvements in MetalWheelHubs, of which the following is a specification, reference beinghad to the accompanying drawings, forming a part thereof.

This invention relates particularly to means for attaching wire spokesto hub-barrels.

The main object of the invention is to produce a simple and effectivehub-flange and spoke-fastening in a single piece from sheet metal.

It consists in certain novel features of construction, and in thepeculiar arrangement of parts hereinafter particularly described, andpointed out in the claims.

In the accompanying drawings like letters designate the same parts inthe several figures.

Figure 1 is a side elevation and section of a wheel-hub embodying myinvention, the plane of the section of the left-hand flange beingindicated by the vertical dotted line 1 1 and the plane of theright-hand flange being indicated by the oblique dotted line 1 1, Fig.2. Fig. 2 is a cross-section of the hub next to one of its flanges,which is seen as viewed from the center of the hub. Fig. 3 is an insideview of one of the hub-flanges and spokefastenings detached. Fig. 4 isan edge view thereof; and Fig. 5 is a section on the line 5 5, Fig. 2.

a is the hub-barrel, which consists of a straight metal tube or sleeve,formed near the ends with external protuberances b to determine theposition of the flanges and to assist in holding them in place thereon.

a c are the flanges for the attachment of the spokes to the barrel a.The flanges herein shown and described are designed to be used inconnection with what are known as return-bend F spokes that is,wir'espokes which are connected in pairs at their inner ends by loops orbends. Each flange 0 consists of a single piece of sheet metal having acentral flanged opening, an outward bend d, con- Serial No. 108,299. (Nomodel.)

centric with said opening, and an inturned notched rim 6, forming withsaid benda sand band or guard on the outer side, and an annular spokeabutment and seat on the inner side, of the flange. The flange 1) aroundthe central opening of the spoke-fastening is preferably turned outwardand is made of sufficient width to afford a firm bearing upon andefficient attachment to the barrel a.

The connecting bends or loops g at the inner ends of the spokes h arecurved to correspond with and fit into the annular seats in the flangesor fastenings c, and the adjacent parts of the inturned rims e, whichare preferably wider or extend beyond the remaining intermediate partsof said rim, are clasped inwardly over the loops or bends g of thespokes, as shown in Figs. 2 and 5, thereby holding them securely intheir seats against the 0pposing bends cl. It will be understood thatall parts of the notched rims e are primarily bent inward parallel withthe axis of the hub, as shown in Figs. 3 and 4E, and after the spokesare placed in position, with their loops or bends g in the annular seatsof the flanges, the wider or adjacent parts of said rims are bent towardthe center of the hub andclasped over the loops or bends of the spokes.

The notches in the rims 6, through which the spokes pass radiallyoutward from their connecting-bends g, prevent any possibility of theslipping of said bends in their annular seats and the circumferentialdisplacement of the spokes in the flanges or fastenings c.

The construction herein shown and described admits of the hub-flange andspokefastening being economically stamped in a single piece from sheetmetal and aitords a neat and effective device for the purpose.

I claim 1. A metallic hub-flange and spoke-fastening for wheelsconsisting of a single piece having a flanged central opening forattachment to a hub-barrel, an outward alinular bend concentric withsaid central opening and forming a sand band or guard on the outer sideand a spoke seat or abutment on the inner side of the flange, and aninwardly-bent rim notched to receive radiating spokes, parts of said rimbeing adapted to fold over the looped inner ends of the spokes and-toclasp and hold them against said seat or abutment, substantially asdescribed.

2. A metallic hub-flange and spoke-fastening consisting of a singlepiece having a flanged central opening, an outward annular bend forminga guard on one side and aspokeseat on the other side of the flange,concentric with its central opening, and an inwardly-bent notched rim,parts of said rim projecting beyond remaining alternate parts andadapted to be clasped over the inner looped ends of wheel-spokes,substantially as described.

3. In a metal wheel-hub the combination with a tube or barrel, of twospoke-fastening flanges each consisting of a single piece of sheet metalhaving a central flanged opening in which one end of said tube or barrelis fitted and secured, an outward annular bend and an inturned notchedrim forming a sandband on the outer side and a spoke-seat on the innerside of the flange, and return-bend Wire spokes having their connectingbends or loops fitted in said seat and clasped therein by inturnedportions of said rim, substantially as described.

4. A hub-flange and spoke-fastening consisting of a single piece ofmetal having a central opening, an annular bend and a re- Verselybentnotched rim concentric with the central opening and forming a spoke-seaton one side and a corresponding annular projection on the other side ofthe flange and fastening, substantially as described.

A hub-flange and spoke-fastening consisting of a single piece of metalhaving a central opening, an annular bend and a reversely-bent notchedrim concentric with the central opening and forming a spoke-seat on oneside, and a corresponding annular projection on the other side of theflange and fastening, substantially as described.

In witness whereof I hereto affix my signature in presence of twowitnesses.
